Effects of indirect fertilization on agricultural lands by atmospheric deposition are examined for the four most valuable crops in the US: corn, soybean, wheat, and pasture grasses. A literature search was conducted to find suitable dose-response functions for the effects of fertilization on yield of each crop. Predicted yield changes were computed from the deposition of nitrogen to the soil in addition to nitrogen applied in accordance with current agronomic practices using these dose-response functions. Low to high nitrogen inputs from atmospheric deposition (1 to 7 kg/ha) are expected to increase the average yield of corn by 0.2 to 1.1%, soybean by 0.1 to 0.7%, wheat by 0.1 to 0.4%, and pasture grasses by 1.6 to 14%. Pasture land is predicted to receive the greatest impact because it is usually unfertilized.
